TINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 500,718, dated July 4, 1893.

Application filed June 22| 1892. Serial No. 437,643. (No model.)

To @ZZ whom, it may concern:

Be it known that we, EDWIN NORTON and JOHN Gr. I'IODGSON, citizens of the United States, residing at Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tinning-Machines, of which t-he following is a specification.

Our invention relates to improvements in 1o tinning machines, and more particularly to tinning machines for use in practicing what is commonly known as the palm oil process of manufacturing tin plate and wherein an oil linx is empleyed as contradistinguished I5 from what is known as the acid process wherein an acid is employed as the flux.

The object of our invention is to provide an apparatus of a simple, durable and efficient construction adapted for useu in the o palm oil process and by means of which sheets of iron or steel may be automatically, rapidly and cheaply tinned, thus saving the skilled labor heretofore commonly required in the practice of this process.

z5 To this end our invention consists in the combination with a device for drying, heating and luxing the sheets automatically, of a device for automatically tinning the dried, heated and luxed sheets and means for delivering the sheets automatically and regularly from the drying, heating and luxing device to the sheet carrier or conveyer of the tinning device.

It also consists in connection with a tinning 3 5 pot of an endless conveyeror carrier furnished with grippers or devices for grasping the sheets, and operated automatically to grasp and release the sheets, whereby the sheets are automatically conveyed down into and through the molten tin in the pot.

` It also consists in connection with the tinning pot and sheet carrier in providing the carrier with a series of sheet gripping or holding devices so that a number of sheets may be operated upon simultaneously or immersed in the pot at once.

It also consists in connection with the pot of the tinning rolls mounted therein and the sheet conveyer or carrier for immersing the 5o sheets in the pot, of a device for automatically lifting the sheet into the bite of the lower pair of rolls, and a device for tilting or moving the sheet from the conveyer in position under the rolls, and a guide bon or case to prevent the sheet from buckling,` or bending as it is lifted.

It also consists in connection with the pot and the tinning rolls of a supplemental pot of cooler metal above the rolls through which the sheet is discharged, the molten metal in 6o the two pots communicating together through the opening in the supplemental pot through which the sheets issue.

It also consists in providing the supplemental pot with an air jacket surrounding the same for the purpose of conveniently maintaining the metal in the supplemental pot at a lower temperature than the metal in the main pot.

It further consists in means for supplying 7o a blast of air to the air jacket space surrounding` the supplemental pot.

It further consists in connection with the drying, heating and iiuxing device, the tinning pot and its automatic mechanism of a sheet feed regulating device operated automatically from or in connection with the sheet carrier of the tinning device and whereby feed of the sheets to the sheet drying, heating and liuxing device is made to correspond to 8o the delivery of the sheets from the tinning device, thus preventing any possibility of two sheets entering the tinning device together or at improper intervals.

Oui-invention also consists in the novel devices and novel combinations of parts and devices herein shown and described and more particularly pointed out in the claims.

In the accompanying drawings which form a part of this specification and in which simi- 9o lar letters of reference indicate like parts, Figure l is a vertical longitudinal sectional view of the machine embodying our invention. Fig. 2 is a vertical cross section on line 2 2 of Fig. l. Fig. 3 is a detail plan View 95 showingthe mechanism in the tinning pot. Fig. 4 is a vertical cross section on line 4 4 of Fig. l and showing the sheet conveyer or carrier in elevation. Fig. 5 is a horizontal section on line 5-5 of Fig. 1. Fig.6 is an entoo larged detail View of the sheet carrier or conveyer and its sheet gripping or holding devices. Fig. 7 is an enlarged detail view of the device for lifting the sheets into the bite of the rolls and of the device for tilting the sheet from the path or line of the sheet conveyer into position under the tinning rolls.

In the drawings A represents the frame of the machine, B the tinning pot, C the palm oil or iiux containing vessel, D the drying, heating and iiuxing rolls, E the feed table or chute, F the intermediate sheet delivery device or chute by which the sheets after being dried, heated and liuxed are delivered to the sheet conveyer or vcarrier G in the tinning pot, H the tinning rolls, K the supplemental pot of coolermetal above the tinning rolls, M the sheet lifting device by which the sheets are lifted into the bite of the tinning rolls, N the device for tilting or moving the sheets from the conveyer G into position under the tinning rolls, and P is the device for regulating the feed of the sheets to the machine. These parts are all combined to co-operate together. They may be combined to coact by any suitable intermediate connecting or operating mechanism. In the drawings we have shown however what we believe to be the best way now known to us of operating, connecting and arranging the several devices or parts constituting the combined machine and the various subcombinations.

The palm oil or linx containing vessel, pot or trough C is preferably divided into three compartments c c c2 and with intermediate steam compartments c3 for heating the oil and an overflow compartment c4. The drying, heating and iuxing rolls D are preferably three pairs in number and are hollowed and heated by steam admitted through the steam pipes d which connect through their hollow journals CZ. The rolls are furnished with gears D for driving the same. The white or pickled sheets are taken directly from the water or washing bath and placed upon the feed table E which should preferably be somewhat inclined to permit the surplus water to flow off. And the wet sheets are then passed immediately through or between the pairs of drying, heating and fluxing rolls D. Each successive pair of rolls should be heated to a higher degree than the preceding rolls, so that the water and moisture on the sheets as they enter the first pair of rolls will not, owing to the low temperature of these rolls cause the oil to foam or boil over too violently. The partition c between the first two pairs of rolls D is also extended up to a con* siderable distance to prevent the palm oil boiling over too much into the contiguous compartments of the oil pot C.

The sheet conveyer or carrier G in the tinning pot B consists preferably of an endless link chain and mounted upon or driven by sprocket wheels G on the shafts G2. The shafts G2 are journaled on a movable frame T which lits inside the pot B and is adapted to be lifted bodily out of the same together with rolls H, lifting device M, sheet tilting tin in the pot B.

device N and the supplemental pot K which are also all mounted upon this movable frame T. The sheet carrier or conveyer chain G is furnished at intervals with sheet holding devices g which co-operate with movable grippers g to grasp the sheet by its lower edge and thus conveyit down through the molten The grippers g each have an operating arm or lever g2 which engages a stationary track or cam g2 mounted on the frame T and which operates to close the grippers and hold the same closed. This track or cam g2 is provided with a movable section g4 at its upper end which by its movement serves to close the grippers after the edge of the sheet is entered between the same. By furnishing the cam track with a movable section g4 which closes the grippers byits movement, we are enabled to close the grippers while the carrier remains stationary, thus insuring against displacement of the sheet before the grippers close upon its edge. The track or cam g3 terminates near the lower end of the conveyer G or its lower sprocket wheel G so that the movable gripper g may open whenthe conveyer G carries it beyond the end of the track g2, and thus release the sheet and permit it to be swung or moved over by the device N into position under the tinning rolls H. The sheet tilting or moving device N consists preferably of a series of fingers or arms secured to a rock shaft n mounted on the movable frame T. The sheet moving or tilting arms N co-operate with a guide box N which is fixed immovably on the frame T in position under the rolls H. The arms N operate to swing or move the sheet over against the guide N. The guide N is, or should be provided with guide flanges or wings N2 at each end, so that the sheet cannot get ont of position. The arms N swing back and forth between the guide flanges N2 of the box or guide N. After the sheet having been first released from the grippers has been swung over into position under the guide rolls H it is next lifted into the bite of the lower pair of rolls H by the sheet lifter M, the same consisting of two or more horizontal fingers projecting between the arms N and into slots formed in the guide N so as to lift the sheet between the guide N and the arms N, the sheet being thus held in a true plane and prevented from buckling or binding by these cooperating devices Nand N. The lifter M is secured to or carried by a reciprocating slide M which is furnished with guide slots m and is mounted upon the shaft G2 of vthe lower sprocket wheel and on the rock shaft n by which the sheet tilting ormoving device N is actuated. The tracks or cams g2 are attached to lugs t on the frame T by brackets t. The movable section g4 of the cam or track g3 is provided with an operating arm or lever g5 and is actuated by a cam S on the cam shaft S through a lever g6 and connecting link g7. The lifting device M is operated at intervals from the cam S2 on the cam shaft S through IOO IIO

the lever m and connecting link m2. The sheet tilting or moving device N is operated from the rock shaft "a6 through an arm n seshaft S, lever n3 connecting link n4 which is pivoted at its lower end to an arm n on the rock shaft ns. y

The tinning rolls H are mounted in suitable bearings h on the frame T and are driven by connecting gears h2 h3 on the shafts of said rolls, and the bevel gears h4 h5 h6 h7 h8 77.9, the latter gear being on the driving shaft R, the gears 71,7 71,8 on the intermediate horizontal shaft 71.10 and the gears h5 h4 on the intermediate vertical shaft hu. to the molten tin in the pot B to connect with the beveled gear h4 on the shaft of the roll H.

The supplemental p'ot K is mounted on or secured to the removable frame T in the upper part of the pot B and just above the tinning rolls H. It is provided with a slot or opening 7a which registers with the rolls H and through which the sheets pass upward into and throughthe supplemental pot and are thus discharged from the machine.

The supplemental pot K is provided with an air jacket K or other suitable means for keeping the molten tin or metal in this supplemental pot at a somewhat lower temperature than that in the main tinning pot B.

K2 is an air blast pipe for supplying a blast or current of fresh or cool air to the air jacket space and thus aid in keeping the temperature of the supplemental pot at the required degree. The supplemental pot K is also preferably furnished with a lip or iiange k overlapping the air space K to guard against the molten metal dripping or dropping into this air space as the tinned sheets are removed or lifted away.

The cam shaft S is furnished with a cam S4v which operates at suitable intervals the feeder P through the leverp connecting link p and rock shaft p2 furnished with arm p3.

The sheet conveyer or carrier G or its Lipper sprocket wheel shaft G is intermittently driven from the main shaft S by means of a crank 99, connecting link or pitman glo, pawl arm g11 on shaft 912, pawl Q13, ratchet g14 on said shaft gw, bevel gears Q15 gw, the latter being on the vertical shaft g, and bevel gears g1S gw, the latter being on the shaft G2.

It` will be observed that the sheet carrier or conveyer G has a series of sheet holders g and grippers g', so that a number of sheets may be operated upon at the same time, in continued succession of steps, one sheet being at. one step or stage of the operation while another sheetis at another step or stage of the complete operation. By this means two or more sheets are immersed in the molten metal at the same time, or all the time, and still no part of the machine separately considered contains or handles but one sheet at a time, that is to say one sheet may be received by the grippers while an- This latter shaft extends down otherI is held by the grippers immersed in the molten metal in the middle of the pot, while another sheet is being released from the grippers and moved into position under the tinning rolls at the bottom portion of the pot, and still another sheet is being discharged by the rol-ls through the supplemental pot and delivered from the machine, and at the same time still another sheet is being operated upon by the drying, heating and fluxing device. By this means as the sheets pass along through the tinning pot in a continued succession, one by one, there is no danger of the sheet handling mechanism which is immersed in the molten metal becoming clogged with the sheets.

By providing the tinning pot B with a supplemental pot K of cooler metal through which the sheets pass after leaving the tinning rolls H the sheets may be completely tinned on their way out of the pot B and by the sameoperation, thus saving the labor of delivering the sheets into a separate pot of cooler metal. l

The brackets or arms t which connect the gripper operating tracks orcams g3 with the frame T are preferably spring or yielding arms so as to slightly cushion the action of the grippers and thus insure the smooth and easy running of the machine and the proper holding action of the grippers at all times.

The links G3 of the chain carrier G, upon which the grippers are mounted, are preferably provided with guide rolls G4 which engage or co-operate with a stationary guide track G5 secured to the frame T so as to hold the chain or the grippers carried therebyin proper coactive relation with the cam track g3.

The grippers g are so pivoted or mounted on the carrier G that they will normally open by their own gravity when not engaged by the cam or track g3; but to insure the positive opening of the gripper at the point or station where the sheets are received between the two opposin g jaws of the gripper, we provide the machine with a gripper opening device V, the same consisting preferably of a spring in contact with which the gripper is brought by the movement of the carrier G.

By providing the machine with a guide or box N and the coacting guide arms N, which when swung over in position beneath the tinning rolls H leaves simply a narrow space for the sheet or plate to fit and be lifted in, the machine is adapted to operate practically and with success upon very thin plates, such for example as those used in the manufacture of taggers tin, as these thin plates are supported and guided on both sides while being lifted into the bite of the rolls on one side by the guide box N and on the other side by the sheet moving and guide arms N. The guide box N by its end anges N2 also guides the sheets at its ends and prevents any possibility of displacement.

By means of this machine each and every sheet or" plate is treated exactly alike, being subjected to the same amount of heat for the IOO IIO

same length of time inthe heating, drying and iiuxing device of the machine, and each and every sheet being also subjected to the tinning bath fora like period of time, so that all the sheets are uniformly and perfectly tinned, While at the same time no skilled labor is required, the machine itself determining by its operation when the sheet is properly heated, properly dried, properly fluxed, and when it has been subjected to the bath of moltentinasuflicient length of timeto be properly tinned. By the movable feed sheet stop or regulating device P the rapidity or rate at which the sheets may be fed to the machine is also automatically regulated and determined so that a boy may be employed for operating the machine. As the sheets are discharged or delivered from the machine through the supplemental pot K of cooler metal, they are grasped by the attendant with suitable tongs and placed upon the cooling racks or in a subsequent linishing machine, if it is desired to give the sheets a further linish. The cam shaft S is driven from the main driving shaft R by beveled gears R R2 connecting the same.

By mounting the mechanism for conveying and handling the sheet in and through the molten metal in the tinning pot on a separate removable frame T adapted to be lifted bodily out of the tinning pot, we are enabled to very easily and quickly examine the mechanism and repair or adjust it when desired. This feature is a matter of great practical convenience and results in a great saving of time and labor as by this improvement it is unnecessary to draw the molten metal out of the pot in order to examine, repair or adjust the mechanism.

The frame T is furnished with eyes or hooks t3 to enable it to be conveniently lifted ont of the pot. lugs b for the frame T to fit upon.
